Rust Program to Calculate the intersection of two sets

Calculate the intersection of two sets

Rust Programming Language

Problem

Rust program that calculates the intersection of two sets using the HashSet data structure.

Input

use std::collections::HashSet;

fn main() {

    let set1: HashSet<i32> = vec![1, 2, 3, 4, 5].into_iter().collect();

    let set2: HashSet<i32> = vec![3, 4, 5, 6, 7].into_iter().collect();

    let intersection = set1.intersection(&set2);

    let intersection_vec: Vec<&i32> = intersection.collect();

    println!("Intersection: {:?}", intersection_vec);

}{codeBox}

Output

Intersection: [3, 4, 5]{codeBox}

Explanation

This program creates two sets, set1 and set2, using HashSet. It then calculates their intersection using the intersection method provided by HashSet. Finally, it collects the intersection into a vector, intersection_vec, and prints it out.
